Earn from the agents reading your site.

AI agents already read your pages, docs and APIs and pay you nothing. With clue, one ad travels along when an agent reads, and you receive 65% of what the advertiser pays. Human visitors see the page unchanged.

Free to create an account. Withdraw from $50 by PayPal, bank transfer or Stripe.

What publishers get

Invisible to humans

Only agent requests get an ad. Your layout, design and existing banners stay as they are.

You keep 65%

65% of what the advertiser pays is credited on every paid event. The console also shows which agents read your pages and how often.

A few lines to install

Pick a website tag, a Node, Python, Go or PHP server, a Cloudflare Worker, llms.txt or an MCP server. Try test mode first.

Three steps to start

From registering your site to the first payout, a few lines of code.

Docs
01

Register your site, API or MCP server and get a site key

Earnings accrue every time an agent reads

Example: an agent opens one ad link from your page, the advertiser pays $0.19 and $0.12 lands in your account.

What clue does

A person asks, the agent reads your page, and the ad rides along into the answer. Human visitors see nothing.
